Effects of Asparagus Powder Addition on Dough and Noodles Properties

In order to realize the comprehensive utilization of asparagus and its by-products, asparagus was dried to prepare asparagus powder and used for the preparation of noodles. The effects of asparagus powder addition (0~10%) on solvent retention capacity (SRC) of mixed powder, water absorption rate, formation time, stability time, weakening degree, retrogradation value of dough, cooking time, water absorption rate, breaking rate, loss rate after cooking, shear force, tensile strength, protein secondary structure and starch digestibility of noodles were systematically studied. It was found that as the amount of asparagus powder added increased, the SRC of the mixed powder increased. Distilled water, sucrose, sodium carbonate, and lactic acid SRC were 79.30%, 111.92%, 99.07%, and 94.34%, respectively, when the amount of asparagus powder added was 10%. The weakening degree C1-C2 value of the dough increased with the increase of asparagus powder addition, reaching a maximum of 799.33 mN·m at 10%, while the retrograd
